Suppose you have 100.00 mL of a solution of a dye and transfer 2.00 mL of the solution to a 100.00 mL volumetric flask. After adding water to the 100.00 mL mark, you take 5.00 mL of that solution and again dilute to 100.00 mL. If you find the dye concentration in the final diluted sample is 0.000129 M, what was the dye concentration in the original solution? Concentration

a) What is the resulting nitrate ion concentration of the diluted solution if 24.00 mL of a 0.514 M sodium nitrate solution is diluted to a total volume of 350.00 mL? Note that this problem is asking for the concentration of the ion (after the salt dissolves) and not the concentration of the salt. Enter units. b) What is the resulting ammonium ion concentration of the diluted solution if 50.00 mL of a 0.572 M ammonium carbonate solution is diluted...

A student adds 50.0 mL of H2O to 25.0 mL of 0.881 M Ca(OH)2. a) what is the concentration of Ca 2+ in the diluted solution? b) What is the concentration of hydroxide ion in the diluted solution? So far I have solved for the concentration of H2O M1V1 = M2V2 --> M(50.0) = 25.0(.881) M1= 0.441 M H2O I just do not know where to go from there.
